Congress Blue (#0B4190) presents certain accessibility challenges that web developers should carefully consider. Its relatively low luminance can result in insufficient contrast against lighter backgrounds, potentially making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's crucial to evaluate the contrast ratio of Congress Blue against the intended background color using online contrast checkers. If the contrast is insufficient, developers should explore alternative color combinations or implement adjustments, such as darkening the text or lightening the background, to ensure readability and a positive user experience for everyone, especially those with low vision or color blindness. Providing sufficient contrast is not only an accessibility best practice but also improves overall usability.
